Level Of Processing

Abstract Cereals and cereal products have a long history of use by humans. Recently, there have been some discussions regarding level of processing as a descriptor to define food products, including cereal-based foods. This has led to a somewhat emotional debate on food processing. Given the widespread inclusion of cereals in the diet, this review highlights the history of cereal processing as well as their consumption by humans. It provides an evidence-based discussion on their production, contribution to human nutrition, benefits and disadvantages. The present review illustrates the impact of processing on nutrients, as well as non-nutrients specifically in bread and ready-to-eat breakfast cereals (RTEC), two cereal-based foods which are widely consumed and integral parts of food-based dietary guidelines globally. As a category, most cereals must be processed in some way to enable consumption by humans as we are not equipped to survive exclusively on raw grains. Even thousands of years ago, the processing of cereals was a common practice by humans, turning raw grains into palatable, safe and nutritious foods. Modern processes for cereal-based products are efficient in providing safe and good-quality products to satisfy population needs, as well as helping to meet consumer expectations by providing a range of foods that allows for a varied and balanced diet. Today, RTEC and bread make significant contributions to dietary energy and nutrient requirements and underpin food-based dietary guidance globally. They have been positively linked with intake of dietary fibre, vitamins and minerals, especially when consumed as whole grain.

AbstractIntroductionThere is a long history of use for whole grain cereals as part of human dietary intakes with records of dietary grain consumption from the Middle Stone Ages. Whole grains are nutrient dense and research demonstrates that the healthiest diets (those associated with reduced risk of non-communicable diseases e.g. cardiovascular disease or cancer) are characterised by higher intake of fruit, vegetables, nuts and legumes and whole grains and lower intakes of red and processed meats. Currently, grains are a main energy and carbohydrate source and as such form a cornerstone of food based dietary guidelines and dietary guidance globally. However, grains also naturally contain contaminants and as a food category can represent a significant dietary source of foodborne contaminants.Materials and MethodsThe outcomes of a narrative review on the major contaminants present in whole grains, their potential health risks and suggested strategies to mitigate any risk are described. Contaminants are limited to mycotoxins (aflatoxinB1, ochratoxin A, Fumonisin B1, deoxynivalenol, zearalenone), heavy metals (e.g. arsenic, cadmium, lead) and the process contaminant acrylamide.ResultsWhole grains can contain more contaminants than refined versions e.g. whole grain rice with bran intact can have up to 80% more arsenic than white rice. However, whole grains also provide more nutrients which may mitigate against the impact of these contaminants. For example, for heavy metals, there is some evidence that dietary fibres (e.g. wheat bran) may bind to them and reduce their absorption, as can nutrients naturally found in whole grains e.g. zinc, magnesium or copper. Minerals such as iron, calcium, magnesium and zinc may also impede heavy metal absorption by down-regulating or competing for attachment to transporters that facilitate intestinal absorption. Although, strict regulatory thresholds and monitoring processes by competent authorities minimise any risk to public health, the consumer may further lessen any risk through their own dietary choices and food storage and preparation practicesDiscussionThere are a number of potential health-protective properties inherent to whole grains. Given that complete elimination of contaminants from grains is unlikely to be achieved, their presence merits continued monitoring with evidence to date suggesting any such risk does not outweigh the known benefits of wholegrain consumption.

Application Specific

Computational modeling and simulation are paramount to modern science. Computational models often replace physical experiments that are prohibitively expensive, dangerous, or occur at extreme scales. Thus, it is critical that these models accurately represent and can be used as replacements for reality. This paper provides an analysis of metrics that may be used to determine the validity of a computational model. While some metrics have a direct physical meaning and a long history of use, others, especially those that compare probabilistic data, are more difficult to interpret. Furthermore, the process of model validation is often application-specific, making the procedure itself challenging and the results difficult to defend. We therefore provide guidance and recommendations as to which validation metric to use, as well as how to use and decipher the results. An example is included that compares interpretations of various metrics and demonstrates the impact of model and experimental uncertainty on validation processes.

This contribution provides a personal overview and summary of Faraday Discussion 172 on “Carbon in Electrochemistry”, covering some of the key points made at the meeting within the broader context of other recent developments on carbon materials for electrochemical applications. Although carbon electrodes have a long history of use in electrochemistry, methods and techniques are only just becoming available that can test long-established models and identify key features for further exploration. This Discussion has highlighted the need for a better understanding of the impact of surface structure, defects, local density of electronic states, and surface functionality and contamination, in order to advance fundamental knowledge of various electrochemical processes and phenomena at carbon electrodes. These developments cut across important materials such as graphene, carbon nanotubes, conducting diamond and high surface area carbon materials. With more detailed pictures of structural and electronic controls of electrochemistry at carbon electrodes (and electrodes generally), will come rational advances in various technological applications, from sensors to energy technology (particularly batteries, supercapacitors and fuel cells), that have been well-illustrated at this Discussion.

The Impact

Background and context: Dietary whole grain (WG) intake helps prevent noncommunicable diseases (NCDs) such as cancers. However, 92.4% of the global adult population does not meet WG recommendations, and WG intake even decreased between 1990 and 2010. In Denmark, WG intake was similarly decreasing during the 1990s and 2000s, and the Whole Grain Partnership (WGP) was established in 2009 to counteract this development. Aim: To describe the development of this public-private partnership (PPP), the results achieved so far, lessons learned and implications for future initiatives. Strategy/Tactics: The strategy is twofold: increasing availability of WG and campaigning about the health benefits of WG. Program/Policy process: · Research and documentation of WG health benefits · Initiate partnership and functioning of organization and secretariat · Ensure clear WG definitions and dietary guidelines · Set targets and success criteria and monitor progress · Create incentives for industry to reformulate and develop new WG products and make it easy for consumers to identify WG product by developing and endorsing a WG logo · Gradually enriching all bread and flour with WG · Develop education materials for chefs, waiters, bakers, in-store personnel and health professionals · Yearly consumer campaigns. Outcomes: Mean WG intake has near doubled in less than 10 years (from 32 in 2009 to 61 g/day 2017). The increment in intake were also significant among the population groups eating the least WG. The number of WG products increased in this period from 150 to currently 800. Continuous monitoring of consumer behavior show a high knowledge, trust and use of the WG logo has increased during the period. What was learned: · To make the PPP work effectively it is crucial to work evidence based, set realistic targets, reinforce the reasons and advantages for partnering, measure and celebrate progress · The impact on population dietary habits is primarily due to the increased availability of WG product combined with a long-term campaigning activity promoting WG health benefits.

The Impact

A balanced diet is a fundamental component of athletes’ health, training, and performance. The majority of athletes choose adequate quantities of macronutrients but, at the same time, do not respect World Health Organization dietary guidelines, eating a lot of discretionary food and not drinking enough water. Athletes need more nutritional education to improve the quality of their food choice. By modifying their eating habits, they could also enhance their performance. Our study aimed to evaluate the impact of nutritional intervention on eating habits in a group of Northern Italian athletes. A sample of 87 athletes (41 males and 46 females) aged 16.5 ± 2.9 was enrolled. We organized meetings and detected eating habits (before and after the meetings) using a food frequencies questionnaire. We found that nutritional intervention positively affected participants consumption of vegetables (p < 0.05), nuts (p < 0.001), legumes (p < 0.001), and fish (p < 0.05). Other aspects of the athletes’ eating habits were not significantly improved. Some gender differences were found; males increased their consumption of vegetables (p < 0.05) and nuts (p < 0.001), while females increased their intake of legumes (p < 0.001). Our finding suggested that nutritional intervention could promote healthy eating habits among athletes. If sports nutrition experts, coaches, personal trainers, sports medicine experts, and athletes cooperated, they could guarantee athletes’ health status.

Parental Health Status

Although the problem of childhood obesity has been broadly documented over the last decades and characterized as one of the most significant problems of public health, the percentage of overweight and obese children remains extremely high. It is undeniable that parents contribute significantly in shaping children’s dietary behavior and can be a valuable factor for implementing effective strategies. However the influence of parental health status on children’s eating habits is another aspect that remains almost uninvestigated. The aim of the study is to examine to what extend parental diet-related chronic diseases affect their own but also their children dietary behavior. A literature review was conducted focusing on studies published within the last decade. The majority of studies examined,indicated a moderate to very low adherence to dietary guidelines for a specific disease, as a result children’s dietary behavior is not favorably affected.Therefore we should emphasize on the importance of healthy dietary modeling especially in case of a family history of disease.

The Impact

People have always had to rely on hunting and gathering for food, fuel and shelter. The first evidence for possible major impact of these activities is the early Holocene extinction of most megafauna on all continents except Africa. Multidisciplinary historical research indicates that both climate and human impact interacted to cause these extinctions. This chapter also discusses historical records which have elucidated some of the long-term impacts of harvesting fish and other creatures of seas and estuaries on aspects such as population numbers, age structure, and species diversity of these organisms. On land, hunting has continued to affect many species. Agriculture, rather than decreasing the use of natural resources, has altered land use and increased demand so that the impact on natural resources has increased worldwide. Industrialization further accelerated this trend. Even those sites removed from active use by inclusion in preserves continue to change, in part because of a complex history of use before they were preserved. Understanding this history can help set appropriate goals for preservation as well as indications of management that may assist in evaluating changes.

Health messages may be an important predictor in the selection of healthier food choices among young adults. The primary objective of our study is to test the impact of labeling whole grain pasta with a health message descriptor displayed at the point-of-purchase (POP) on consumer choice in a campus dining setting. The study was conducted in a large US college dining venue during lunch service; data were collected during a nine-week period, for a total of 18 days of observation. Each day, an information treatment (i.e., no-message condition; vitamin message; fiber message) was alternated assigned to whole grain penne. Over the study period, the selection of four pasta options (white penne, whole grain penne, spinach fettuccine, and tortellini) were recorded and compiled for analysis. Logistic regression and pairwise comparison analyses were performed to estimate the impact of health messages on diners’ decisions to choose whole grain penne among the four pasta types. Our results indicate that only the message about vitamin benefits had a significant effect on this choice, with a 7.4% higher probability of selecting this pasta than the no-message condition and 6.0% higher than the fiber message condition. These findings suggest that psychological health claims (e.g., reduction of fatigue) of whole grains seem more attractive than physiological health claims (e.g., maintaining a healthy weight) for university students. In line with the 2015–2020 Dietary Guidelines for Americans, our results suggest that small changes made at the POP have the potential to contribute to significant improvements in diet (e.g., achieving recommended levels of dietary fiber). These findings have important implications for food service practitioners in delivering information with the greatest impact on healthy food choices.

The paper presents the results of research on the degradation of chernozems in part of the Proszowice lobe (near Pińczów). The currently progressing process of degradation of chernozems is showed in the decline of their physical and chemical properties (among others increased predisposition to soaking, changes in the content of organic carbon and nitrogen). The results were analyzed in the context of changes in the technology of farming. For the analysis, samples from areas with different types of use and different history of use (including archaeological sites) were collected. A significant decline of soil properties was found. They were expressed by destruction of the soil structure of humus horizon. It starts increase in the susceptibility of the soil clumping, soaking and erosion. The humus contents in researched samples are low (as content for Chernozem), but there is no different in this parameter determined half century ago. Currently, low values of the C/N coefficient indicate the impact of mineral fertilization (increasing the nitrogen content) and are part of the anthropogenic degradation of the analyzed Chernozems.

Abstract. Background: Self-esteem is a major contributor to risk for repeated suicide attempts. Prior research has shown that awareness of stigma is associated with reduced self-esteem among people with mental illness. No prior studies have examined the association between self-esteem and stereotype awareness among individuals with past suicide attempts. Aims: To understand the relationship between stereotype awareness and self-esteem among young adults who have and have not attempted suicide. Method: Computerized surveys were administered to college students (N = 637). Linear regression analyses were used to test associations between self-esteem and stereotype awareness, attempt history, and their interaction. Results: There was a significant stereotype awareness by attempt interaction (β = –.74, p = .006) in the regression analysis. The interaction was explained by a stronger negative association between stereotype awareness and self-esteem among individuals with past suicide attempts (β = –.50, p = .013) compared with those without attempts (β = –.09, p = .037). Conclusion: Stigma is associated with lower self-esteem within this high-functioning sample of young adults with histories of suicide attempts. Alleviating the impact of stigma at the individual (clinical) or community (public health) levels may improve self-esteem among this high-risk population, which could potentially influence subsequent suicide risk.
